CAR-AXLE LUBRICATOR.

-lEClECATION forming part of Letters Patent No. 315,002l dated April 7, 1885.

Application iiled February 6, 1885.

To @ZZ whom t may concern:

Be it known that l, liRAs'rUs L. CLnvE- LAND, a citizen ofthe United States, residing at Pittsburg, in the county ol' Allegheny and and useful improvement in Oar-Axle Lubrieators, of which the following is a specification, reference being had to the accompanying eration, and one that will not be likely to get` out of order.

Vith these ends in View the invention consists in the` improv-ed construction and combinations of parts, hereinafter fully described, and pointed out in the claims.

ln the drawings, Figure lis aside elevation of a lubricator constructed in accordance with my invention. Fig. 2 is a longitudinal vertical section of the same. Fig. 3 is a horizontal section, Fig. 4. is a central vertical transverse section, and Fig. 5 is a detail view, of the brush-shaft and brush.

ln the accompanying drawings, in which like letters of reference indicate corresponding parts in all the iigures, A represents a box or casing, which is preferably constructed of metal, said casin g being substantially rectanguv3 5 lar in form, and having at its upper end oppositely-extending lianges c, provided with holes or openings for the passage of screws or their equivalent, for securing a cap or cover, b, in place. The said box or casing A is divided into two compartments or chambers by a wall, B, which extends from side to side, said wall being of any suitable form, in the present case substantially U shape, the outer chamber, b, serving as the oil-chamber, while the chamber 4 5 b contains the brush for lubricating the shaft or axle, said chamber b being open at its upper end.

lUpon one side of the box 'or casing A are formed holes or openings c, which communicate with the oil-chamber b, and in said holes State of Pennsylvania, have invented a new,

(No model.)

or openings are fitted short pipes or tubes d, having on their upper sides` at the outer ends thereof, upwardly -extending ears, to which are pivoted caps or covers e, adapted to close said openings and be thrown to one side, so that oil may be supplied to said chamber b.

ln the lower end ofthe partition-wall B is provided a slot or opening in which is fitted wicking or waste which projects into both the chambers b b. i

Upon the inner faces of the side walls of the chambers b are provided guides or ways f, in which slide plates C, having circular recesses or openings g.

At the lower ends ofthe plates C are provided downwardly-extending pins It, which iit in spiral springs fi, held in place on the bottom of cham ber b by upwardly-extending pins j located thereon.

D represents the brush-shaft, which is provided near each end with a friction-disk, k. The said shaft D is provided between the fric tion-disks k with an opening extending entirely through the same, and holes or openings are made in said shaft, which openings communicate with the longitudinal openings l.

In the opening lare plates m, having side flanges, which bear against the sides of the brush-shaft, and between said plates is fitted the brush, which may be of bristles, Wire, or 8O other material, and said brush is clamped in the hole or opening l by means of -screws n, which work in the openings mentioned and bear against the plates m. The bruslrshaft is located in the recesses or openings in the plates O, and as there are springs located beneath the same, it will be seen that a yielding bearing is afforded said brush-shaft.

E represents a shaft or axle, which is formed with frictioudisks o, adapted to engage the friction-disks 7cv on the brush-shaft, and said shalt is held in place and in engagement with said friction-disks by means of a box or bearing-bracket extending downwardly from'the under side of the top or cover and having a re 9 5 cess to receive the shaft.

The operation is as follows: The axle or shaft E, in revolving through the medium of the friction-disks, imparts motion to the brushshaft, which revolves, and the ends of the roo brush run against the wicking and take therefrom a quantity of oil, the oil being drawn to the top of the wicking by capillary attraction. The ends of the brush bear or rub against the axle or shai't E in revolving, and thus lubricate the same.

The abovedescribed lubricator is simple in its construction7 effective in its operation, strong and durable, and not likely to get out of order.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent. is-

l. The brush-shaft having an elongated opening, and plates having side iianges located in said opening, in combination with Ya brush located between said plates, and setscrews adapted to bear against the latter, substautially as set forth.

2. The brushshaft having an opening and clamping-plates located in said opening, in combination with a brush located' between said plates, substantially as set forth.

3. The lubricator consisting of a box divided by a partition-wall into two chambers, the outer chamber surrounding the lower end and sides of the inner compartment, an opening in the partition-wall, and a wick located in said opening, in combination with a brush and shaft located in the `inner chamber, sub stantially as set forth.

4. The brush-shaft and brush, in combination with a lubricating box or casing divided into two compartments and a wicking establishing communication between the same, substantially as set forth.

5. The combination, with the box or casing divided into two compartments, of' yielding bearings within the inner compartments, a brush-shaft and brush, and a wicking located in a slot in the partition-wall, substantially as set i'orth.

6. The combination, with the box or casing divided into two compartments, of the brush-shaft and brush mounted in yielding bearings located within the inner casing, said brush-shaft being adapted to be revolved by the shaft or axle to be lubricated, substantially as set forth.

7. The combination, with the box or casing divided into two compartments, and a wicking located in the slot of the partitionwall, of the brush-shaft located in yielding bearings, the brush, and friction-disks on said brush-shaft adapted to engage friction-disks onthe axle or shaft to be lubricated, substantially as set forth.

8. ln a lubricator, the combination, with a box or casing, of a brush-shaft and brush, said brush-shaft being mounted in yielding bearings within the casing, and friction-disks on said brush-shaft adapted to be revolved by disks on the shaft to be lubricated, substalr tially as set forth.

9. The combination, in a lubricator, with a box or casing divided into two compartments,

and a wick establishing communication be- Y tween the saine, of a bruslrshaft carrying a brush, and located in yielding bearings within the inner compartment of the box or casing, friction-disks on said lnush-shaft, and an axle having disks to engage the same, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto aiiixed my signature in presence of two witnesses.
